Design for a Hyper-Local Student Marketplace
CampusNex was built to solve the fragmentation of campus commerce—moving students away from unsecure social media groups into a dedicated, safe, and efficient marketplace. The challenge: build an MVP that balances the trust requirements of peer-to-peer trading with the speed of a modern e-commerce experience, tailored specifically to the financial constraints of the student demographic.
As the Lead Product Designer and PM, I architected the core marketplace engine and secure "Campus-Only" verification flow. I designed the high-fidelity mobile experience, developed a modular Product Card system for varied inventory types (books, electronics, furniture), and optimized the checkout flow to facilitate safe physical meet-ups on campus.
This category details the step-by-step approach taken during the project, including research, planning, design, development, testing, and optimization phases.
Navigating Trust (Discovery)
I started with discovery to understand the "Safety Gap" in student trading. Using Erika Hall’s "Just Enough Research," I identified that the primary friction wasn't the price of items, but the fear of scams and the awkwardness of arranging meet-ups. We decided to focus the MVP on Verified Student Profiles, solving the most critical task: ensuring every buyer and seller is a legitimate member of the university community.
lanning the App Structure (Marketplace Hierarchy)
I devised the app structure using Category-Based Information Architecture. Students need to scan vastly different data points for a "Textbook" versus an "iPhone." Aligning on these flows early via hierarchical flowcharts helped us avoid a cluttered UI. I designed a "Smart-Search" pattern that prioritizes items within the user's specific campus residence area, reducing the logistical burden of the trade.
Wireframing: Optimizing the Discovery Loop
"I began by wireframing the 'Marketplace Feed'—the core engine. Following Steve Krug’s 'Don’t Make Me Think,' I prioritized the image and price as the primary visual anchors. By keeping these layouts lo-fi, I was able to stress-test the Grid System, ensuring the UI remained legible even with high-density listings and varying image qualities."
UI Design
With wireframes approved, I moved to UI design, creating development-ready mockups. I defined a strict Atomic Design System featuring high-contrast typography and 'Condition Badges' (New, Used, Like-New). I utilized Saturation Contrast for the 'Buy/Message' buttons to ensure the primary conversion path was always clear."
The challenge was a Cold Start Problem. To achieve liquidity, we needed high signup rates, but to ensure safety (the Founder’s priority), we needed a strict institutional verification gate. I had to design a 'Trust-as-a-Service' flow that verified every user without creating a 'high-friction' barrier that would kill the marketplace’s early-stage growth.
40% Increase
in Completed Trades: By implementing "Safe-Meetup" logic, we increased the likelihood of a successful transaction between students.
100% Student Verification
The institutional email gateway ensured a "zero-scam" environment, fulfilling the Founder's primary safety goal.
25% reduction
The automated dispute-resolution flow projected a in the need for manual marketplace moderation.
